GHABLES L. GLA$S, OF JGPLIN, MISSUURI.

sziovmno-msournn- V To all whom it may concern:

Be it known that I, GHARLESL. GnA ss, a citizen of the United States, and resident of Joplin, Jasper county, Missouri, have invented certain new and useful Improvements in shoveling-Machines, of which the following is a specification, containing a full, clear, andexact description, reference being had to the accompanying drawings, forming shoveling machines,

' vide movable parts carried by the tilting crane and connected with the free end of the ing the motor shovel beam whereby the shovel may be operated in such manner as to be 0 in a vertical space equivalent to tie combined length of the beam and shovel.

A further object of my invention is to construct a machine of the class described in which there is a tilting crane having a fluid motor carried thereby and means for movbodily, relative to the crane in connection with such a shovel having a beam which fulcrums over the end of the crane and is connected with the fluid motor in such manner as to be operative in a vertical space equivalent to the combined length of the shovel and beam.

For the above purposes my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in theclainis and illustrated bythe apcompanying drawings, in which: 1

Figure 1 is an elevation of my improved shoveling apparatus; Fig. 2 is a plan of the complete apparatus; Fig. 3 is an enlarged, transverse, sectional elevation taken on the line 3-3 of FigMQ; Fig. 4 is an enlarged, transverse, sectional elevation, taken on the line of Fig. 2; Fig. 5 is an enlarged, sectional plan taken on the line 5-5 of Fig. 1 ,Fig. 6 is an enlarged, detail, sectional elevation taken on the line 6-6 of Fig. 2, portions of the apparatus being broken away;

and employing tilting crane a to construct a machine erative I Specification of Letters Patent. Patented Sept. 27, 1910. Application filed January 24, 1910. Serial No. 539,789. I

and Fig. 7 'is an elevation of the complete V apparatus showing the shovel and its beam in a position approximately parallel with the tilting crane and showing the fluid motor and parts carried therewith in posit ons approximately at their forward limits of lmovement.

=Referring by numerals to the accom panying drawin 's: 1 designates a wheeled. truck','and 2 designates a member of a turn table which is secured to the truck.

3 designatesthe base section of a movable frame and 4 the upper member of the turn table which is secured to the base section 3 of the movable frame. The base section is preferably constructed of parallel beams, the middle pair of. beams being extended a considerable distance beyond the rear end of the remaining beams. i 1

5 designates uprights which are preferably constructed of angle irons'and converge toward the top of the frame and are united by means of the plates 6. Supported on the top of the frame are the bearings 7 which support and embrace the shaft 8.

9 designates a pair of parallel beams, each i of which carries a bearing 10 which are mounted upon. the shaft 8. The beams 9are preferably I-shape in cross section and constitute together with their support atilting crane.

The beams 9 are maintained at a proper distance of separation by means of 11 which are carried by the the set screws bearings 10 and impmge against the shafts.

The space between the beams 9 is not spanned by any connecting parts except at its rearmost end where the shaft 12 is located, to which shaft the piston rod 13 is pivotally connected.

Secured upon the upper referred to middle beams,

faces of the above bearings is pivotally mounte a cylinder 15 which is provided with the ordinary twoway valves 16-16 which are operated in a common manner by a connecting rod 17, and the valves are supplied with fluid pressure through the pipc 18 and the flexible connection '19 from a suitable source of fluid pres-' of the base section- 3 of the frame, are'the bearings 14, in which J i 21designates rollers which are carried by the straps '20 and are arranged to ride or travel upon the inner lowermost flanges of the beams 9. Trunnions 22 for said rollers 21 are preferably formed integral with-the wheel 30. Said pin-ions are arranged to mesh with the racks 31 fixed to the upper faces of the beams 9 for purposes of moving the cylinder 23, the straps 20 and the parts carried thereby longitudinally relative to the beams for purposes hereinafter made clear.

32 designates the piston rod, the piston of which is mclosed by the cylinder 23and to which piston rod 32 the cross head 33 is secured. Extending through the cross head 33 is a rotatable shaft 34, the outer ends of which are embraced by the flanged rollers 35 which rest and travel upon the upper faces of the beams 9 inadvance or forwardly of the racks 31. Carried by the straps 20 are the reinforcing strips 36 which straps and strips are provided with coinciding bearing openings throu h which the shaft 37 is extended. Carrie by the outer ends of the shaft 37 are the rollers 38 which rest and travel u on the upper face of the inside flanges of t e beams 9. Loosely mounted upon the shaft 37, approximately at its longitudinal center, 18 a pulley 39 which is socured-against movement longitudinally of the shaft by means of the collars 40.

' At the forward end of the straps 20 are the reinforcing plates 41, similar to the strips 36 which are also provided with bearing openings coinciding with similar openings through the straps 20 through which the shaft 42 is extended, and rotatably mounted on the ends of the shaft 42 are the rollers 43. A portion of the shaft 42, between the plates 41, is flattened for a distance equal to the face of the beam 44, the

beam being secured to the shaft 42 by means of the U-bolts-45. The beam 44 is provided at its upper end with a bail 46 to which is secured a flexible member such as a cable 47,

the other end of which cable is secured to an eye 48 carried by the cross head 33.

Secured to the lowermost end of the beam 44 is a pair of outwardly and downwardly extending arms 49, and pivotally carried by the arms 49 is a shovel 50 which is provided with a hinged door 51 and a catch 52 for holding the door closed.

To prevent spreading of the beams 9 forwardly of their pivotal support, I have pro- I tensions 53 terminate in vertically,

flanges 54 which engage the outer base picks.

vided the integral, lateral ex'tensimis:53 carried by the, reinforcing plates 41. The exflanges of each of the beams 9.

To prevent buckling of the beams 9 be pivotal sup orttween the flanges 54 and the of the beams, I have provided therein orcmg strips 36 with integral, lateral extensions 55, which extensions terminate in up-' turned flanges 56, the extensions 55 and flanges 56 being the exact counterparts of the extensions 53 and flanges 54.

The shoveling machine, as hereinbefore described, is primarily desi ed for use in mining, it being understoo that the excayating in drifts must be accomplished with mas small a vertical space as omible for the sake of economy in the hamfiing of the earth or rock above and below the vein or lead bein mined.

By sue a construction of machineas described, I am en'abled to operate av shovel and a beam, the combined lengths of which are nearly equal to the height of the drift. In other words, in an eight foot drift I am enabled to operate a machine employing a shovel and a shovel beam, lengths of which are approximately e' ht feet; such an operation is possible and due to the arrangement of the shovel beam and the tilting crane together with the movable parts carried by the crane, which movable parts operate to move the shovel in a working position in a comparatively small vertical space.

In the practical operation of the machine, the truck 1 is mounted on suitable rails which are arranged lengthwise of the drift and at the approximate transverse center, there being similar rails (not shown) ardispos ed the combined ranged to one or, in some cases, both sides of. the rails which su port the machine, which rails are designed for the moving of the mineral and earth or rock. In mining with such a machine the operation of loosening the earth rock or mineral is carried about in the usual manner as by blasting or, in some cases, by hand, using the miners After,the earth has been loosened sufficiently and it is desired to remove the same, the entire machine is brought to a po- -sition atthe end of the drift and the wheels of the truck 1 are secured in any suitable manner, preferably by wedge shaped blocks (not shown) being placed to the rear of one or more ofithe supporting wheels. The machine is then connected with a suitable source of fluid pressure supply, preferably compressed air, and the operating lever, 17 1s manipulated which permits air to enter be-' hind the piston carried by the rod 13, which action til-ts the entire crane to a position as shown in Fig. l.

To operate the shovel the lever 26 1s macu es ni ulated which permits air to enter the cylinder is locked against movement lngiions 29 caused to tudinally or the crane by any suitable means (not shown) and preferably by wedge shaped blocks which are placed between the supporting wheels and the flange of the beams 9, such a movement of the piston and its rod draws the cross head 33 rearwardly, whichcross head draws the cable 4?,and by reason of the cable being connected with the upper free end of the shovel beam 44 and by reason of the shovel beam being fulcrumed over the end of the straps 2O whlch are fixed immovable relative to the beams 9, the shovel beam and shovel are extended into the mat- .ter to be excavated.

accomplished by a manipulation of the valves controlling the admission of compressed air to the cylinder 15. This operation is continued until the drts assume the position approximately as indicated in Fi 7 and when the parts have assumed suc position the entire machine'is moved on the turntables so position over a car or the like located at the side of the machine.

When it is desired to advance the operative parts Without moving the truck 1, the hand wheel 30 is manipulated and the pinmove upon the racks 31 which movement advances the cylinder 23 and parts carried thereby, the pulley 39 and the beam it, all of which are connected by means of the straps 20.
